More than 2,000 members of the union who will work on building 200 CH-53K King Stallion Helicopters for the next 14 years voted overwhelmingly in favor of a new contract Sunday.

Teamsters 1150 voted 2,104 to accept and 143 to reject a contract with Lockheed Martin that keep helicopter production at the Sikorsky facility in Stratford. It’s unclear still exactly how much the total contract is worth, but a brief summary on the union’s website says all new employees who joined the union after July 1, 2017 will receive a 25 percent reduction in their hourly rates and a one-time $1,500 ratification bonus.

The maximum number of hours worked per week will be 36 hours and anything over 36 hours will be paid as overtime, according to the website. Also the company will contribute 4 percent of their unmatched gross earnings to their pension plan and new employees will receive an additional $1.20 per hour contribution for up to 40 hours per week.

Sunday’s vote was a necessary step in Lockheed Martin’s decision to stay and manufacture the helicopter in Connecticut.

The General Assembly approved a $220 million economic incentive program for the helicopter maker during a one-day special session on Sept. 28.

During debate over why it was necessary to give the company an economic incentive to stay, it was revealed that the cost of doing business in Connecticut was about $400 million more than in other southern states like Florida and South Carolina. The company, according to lawmakers, said it needed to make up the difference in order to produce the helicopter in Stratford.
